First, you're describing Python 2.x ; 3.x is different in a few
ways. For one, int and long are combined into a single type.

Variables don't have types. Only objects have types. A name can be
bound to any object, regardless of its type, or to what it might have
been previously bound.

Otherwise, you're right. Python is a rich language, with "batteries
included." There's a lot in the built-in space, but if you include the
stdlib, it's really rich. And if you include the fact that objects you
define yourself are first-class, there are very few limits.
